Definitions
- the invention relates to an automatic coffee machine, in particular for single cup and jug production, with a continuous-flow heater having a housing for the provision of hot water, with a device for supplying coffee powder, with a brewing device which comprises a tube section arranged in a stationary manner with a vertical axis, and has two brewing pieces formed, which is at least partially arranged in the flow heater and in which at least part of the pipe section of the brewing room is flushed with the hot water of the flow heater, and with an axial drive for the movement of the upper plug in the direction of the axis of the pipe section, one Drive for the movement of the upper locking piece in the park and the ready position in the axis and a vertical drive for the lower locking piece.
- An automatic coffee machine is understood to mean a machine in which the processes of grinding the coffee powder, introducing the coffee powder into the brewing chamber, the brewing process itself and the ejection of the leached coffee powder as well as the pushing out of the leached and squeezed tablet of coffee powder take place automatically without one this or other process steps would have to be triggered or supported manually.
- the coffee machine must be started by pressing a switch or the like in order to carry out a cycle.
- the invention is also applicable to a bulk fresh brewing machine.
- a coffee machine of the type described above is known from DE-PS 38 43 568.
- the upper closure piece of the The brewing device is mounted on a carriage, which in turn can be moved in the horizontal direction on a cover part of the continuous-flow heater, which is designed as a slideway.
- a linearly reciprocating drive is provided for the movement of the upper closure piece in the park and in the standby position in the axis of the pipe section.
- An axial drive for moving the upper closure piece in the direction of the axis of the pipe section is arranged on the carriage, these two drives being set in operation one after the other.
- the upper closure piece is formed in two parts and consists of a supporting part and an at least partially conical centering part, which carries a single seal for closing the brewing chamber on the one hand and for sealing the inlet of the hot water on the other.
- the centering part is mounted on the supporting part so that it can move both axially and radially to a limited extent, in order to enable self-centering at the upper edge of the pipe section, on which the seal is seated after the centering by the centering part as a stop and valve seat.
- the brewing chamber on the one hand and the inlet of the hot water on the other hand are sealed.
- the lower closure piece which is designed in the manner of a piston and is guided in the pipe section, has a vertical drive which has a double-acting, hydraulically actuated piston.
- the linear drive moving exactly radially to the axis of the pipe section must be of relatively large construction, since the drive elements engaging on the upper closure piece and the associated motor must be arranged on the side of the upper closure piece facing away from the pipe section in order, for. B. in the park position not to adjust the upper opening of the pipe section, for example the coffee powder can be introduced freely into the interior of the pipe section.
- the brewing device has a tube section which is arranged with a vertical axis and is already partially arranged in the housing of the instantaneous water heater, so that a largely constant temperature of the outlet temperature of the coffee beverage is achieved regardless of the chronological sequence of individual brewing cycles.
- a one-piece upper closure piece is used, which by means of a single drive both radially to the axis of the pipe section of the brewing chamber and in the direction the axis of the pipe section is arranged movably.
- the closure piece itself is conical and provided with a seal, which only fulfills the function of sealing the brewing chamber upwards, since the hot water supply is provided in the region of the lower closure piece.
- the lower closure piece is also conical and provided with a seal.
- a brewing chamber with conical closure pieces has the disadvantage that it is not possible to move these closure pieces in the tube section like a piston and, for example, to pre-press the loosely filled coffee powder into a tablet. A dry pressing process and a dry ejection are also not possible. Due to the conical design of the two closure pieces, accurate positioning relative to the axis of the pipe section is only of limited importance.
- the brewing chamber consisting of a stationary tubular section with a vertical axis is provided there within a carrier plate, which is connected to a second carrier plate via a construction having guide rods. Hydraulically actuated piston / cylinder units are provided in the second carrier plate, with the aid of which two piston-like closure pieces at each end of the pipe section can be moved into the pipe section or moved in the pipe section.
- a pivotable funnel piece is provided, which is used to introduce the ground coffee powder from the side into the brewing chamber and to remove the leached tablet of coffee powder from the brewing chamber.
- the invention deals with the problem of a in a coffee machine of the type described above To achieve more precise positioning of the upper breech block from the parking position to the ready position and the subsequent brewing position.
- this is achieved in the coffee machine of the type described above in that the upper closure piece is arranged on a rotary arm which is pivotally mounted about a fixed bearing, that the drive for the movement of the upper closure piece in the park and in the standby position Swivel drive is that the upper closure piece is formed in one piece and by means of the axial drive, which is arranged on the rotary arm, can be inserted sealingly into the tube section to reach the brewing position.
- a rotating arm in connection with a swivel drive.
- This rotary arm has a predetermined length, which cannot be changed in this respect, so that the positioning of the upper closure piece with respect to this one coordinate is maintained very precisely and reproducibly.
- the absolute length of the rotating arm ie the distance of its bearing from the vertical axis of the pipe section, is considerably shorter than the support of a linear drive, so that temperature influences and changes in length caused thereby can only have an insignificant effect.
- the arrangement of the bearing of the rotary arm can then take place anyway in a region of the cover part of the continuous-flow heater where temperature differences hardly occur.
- the surface of the cover part as a slideway is advantageously omitted, since sliding contact is avoided.
- the play present in the swivel drive is advantageously used, which the remaining centering of the closure piece to the axis of the Permits pipe section.
- This one-piece designation means that the upper closure piece does not have to have two parts which are movable relative to one another, as is the case in the prior art with regard to a support part and a centering part.
- the one-piece closure piece can be composed of several parts; for example, it must carry a seal and a strainer.
- the upper closure piece can also be moved to the pipe section differently than in the prior art. It is not placed on the upper edge of the pipe section, but is guided over a longer distance so that it can be inserted sealingly into the pipe section. During this movement over a longer contact distance, the play in the swivel drive is used for centering purposes.
- Another advantage is the simpler training with fewer parts.
- the use of a rotary arm in connection with a swivel drive also advantageously leads to the fact that the space required for this arrangement is reduced, so that such a brew group can be used in a very narrow construction.
- the seal provided on the closure piece only has to seal off the brewing space from the outside, even though the upper closure piece carries the inlet for the hot water into the brewing room.
- the fixed bearing of the rotating arm is arranged on the housing of the instantaneous water heater. This guarantees that the heat developed in the instantaneous water heater also controls the temperature of the bearing and the rotating arm so that these parts have an approximately constant temperature during operation. Changes in length of the rotating arm due to different temperatures are thus avoided.
- the swivel drive of the rotary arm can advantageously have an electric motor with a worm gear connected downstream, the electric motor and the worm on the rotary arm and the worm wheel being arranged in a fixed manner on a fixed journal of the bearing.
- This design allows reproducible, on the one hand, precise angular positioning when pivoting the rotating arm.
- the downstream worm gear provides sufficient play for the swivel drive, which enables the locking piece, including the rotating arm, to be centered in the other direction.
- the axial drive for the upper closure piece can also have an electric motor with a worm gear connected downstream and a nut / spindle unit, the worm wheel forming the nut being rotatably mounted on the rotary arm and the one-piece upper closure piece being fastened to the spindle.
- the closure piece or the spindle is guided against rotation in the direction of the axis of the tube section, so that the rotary movement of the nut or the worm wheel is converted into a pure axial movement. This means that significant reductions can also be bridged, so that the end position reached in the brewing position can be reproduced and reached very precisely.
- the two electric motors can be mounted with their axes parallel to one another on the rotating arm. On the one hand, this increases the mass to be moved of the rotating arm or on the rotating arm, on the other hand, the two electric motors can be accommodated in a small space, so that they discharge comparatively little and do not unnecessarily increase the overall width of a brew group.
- the lower closure piece In connection with the special design and the drive of the upper closure piece, there is also an axial drive for the lower closure piece in the form of an electric motor downstream worm gear and a nut / spindle unit.
- the two drives for the vertical movements of the closure pieces can be designed at least similarly, but also identically. This makes it possible to position the lower closure piece, which carries the outlet for the coffee drink, very precisely and also to monitor the respective positions precisely. This is particularly important for the pressing of the coffee powder tablet, a subsequent pressure relief, the control of different tablet heights, as are required for a single cup production in comparison to a jug production, as well as for all other positions of the two closure pieces with respect to one another up to the dry ejection.
- Direct current motors can be advantageously provided as electric motors, which additionally improve the precision and accuracy of the positions reached. Such DC motors are also particularly easy to control.
- An abutment for support purposes can be assigned to the rotary arm. This abutment becomes effective when the rotating arm and the upper closure piece are in the aligned position to the axis of the pipe section and retracted into the pipe section and pressure is exerted via the lower closure piece, i.e. in particular when pressing the coffee powder tablet or when squeezing it. Even greater forces occur when the coffee powder tablet flows through when the brewing pressure is built up. In these cases, the rotary arm is supported on the abutment in order to prevent the rotary arm from moving upward and to absorb the forces better.
- the swivel drive and the axial drive for the upper closure piece are independent of one another, with both drives being provided on the rotating arm and thus also pivoting.
- the two drives are obviously in succession Activity set as the corresponding movement requires.
- At least one wiper, preferably two wipers, is also connected to the rotating arm, so that the pivoting movement is simultaneously used for cleaning coffee powder residues from the surface of the cover part of the instantaneous water heater.
- the second scraper provides additional security and takes away residual amounts of coffee powder that are not fully grasped by the first scraper.
- the tube section forming the brewing chamber can be provided in the lower part of the housing of the water heater, with the outlet for the coffee beverage being connected by means of a hose to the lower closure piece.
- the coffee machine has a water heater 1, the housing of which consists of a lower part 2 and a cover part 3, which are held together by means of a seal and a number of fastening screws. For reasons of clarity, the division is not shown here.
- An interior 4 is thus formed in the interior of the housing 2, 3, in which a heating coil 5 is arranged, by means of which the water located in the interior 4 is heated.
- the cold water enters via a nozzle, not shown, which is provided at the lowest point of the lower part 2.
- a brewing device 7 is accommodated in a bulge 6 of the housing 2, 3.
- This brewing device 7 has a tube section 8 which is cylindrical in shape and whose axis 9 is arranged vertically.
- the pipe section 8 is comparatively thin-walled and sealed with the aid of seals 10 and 11 in relation to the interior 4 in the housing 2, 3 of the continuous-flow heater 1, the pipe section 8 being received and clamped between the lower part 2 and the cover part 3.
- Further essential components of the brewing device 7 are an upper closure piece 12 and a lower piston-like closure piece 13.
- the tube section 8 and the two closure pieces 12 and 13 enclose a brewing space 14 in which the coffee powder, pressed into a tablet, flows through the hot water and thereby the coffee drink is formed.
- the lower closure piece 13 has a seal 15, with which it can be moved in a sealed manner in the tube section 8 in the manner of a piston.
- the closure piece 13 has a sieve 16 for the coffee beverage, with a hose 17 connecting through the sieve 16 through which the coffee beverage to Spout of the coffee machine comes.
- a spindle 18 is connected to the piston-like closure piece 13.
- the vertical drive is transmitted to the lower closure piece 13 by means of a worm gear 19.
- An electric motor 20 (FIG. 3) is provided for this purpose.
- the upper closure piece 12 is in principle formed in one piece and has a single seal 21 and carries a sieve 22 on the side facing the brewing chamber 14.
- the upper closure piece 12 is ultimately suspended by means of a spindle 23 on a rotary arm 24 which is supported by a bearing 25 is pivotally mounted about a vertical axis 26.
- the bearing 25 in a fixed arrangement on the cover part 3 has a bearing pin 27 to which a worm wheel 28 is connected in a rotationally fixed and thus fixed manner.
- a screw 29 is rotatably mounted in the rotating arm 24, for the rotation of which an electric motor 30 (FIG. 3) is provided.
- the pivot arm 24 is pivotally supported on the bearing journal 27 by means of a sleeve 31.
- the one end position of this pivotability in which the upper closure piece 12 is pivoted laterally away from the tube section 8 of the brewing device 7 (FIG. 3), is referred to as the parking position.
- the other end position in which the closure piece 12 is located above the brewing chamber 14 and with the seal 11 not yet inserted into the tube section 8, is referred to as the ready position. If the upper closure piece 12 is then partially inserted into the brewing chamber 14, as shown in FIG. 1, the brewing position is reached.
- a further electric motor 32 (FIG. 3) is initially provided, which, like the electric motor 30, is also mounted on the swivel arm.
- the axes 33 and 34 of the two electric motors 30 and 32 are arranged parallel to one another.
- the electric motor 32 is also initially followed by a worm gear consisting of a worm wheel 35 and a worm 36, the worm 36 being only rotatably mounted on the rotating arm 24 and being driven directly via the output of the electric motor 32.
- the worm wheel 35 is rotatably mounted on the rotary arm 24 with the aid of indicated ball bearings and, together with an internal thread 37, which can be designed as a trapezoidal thread, also forms a nut in which the spindle 23 is suspended with the associated external thread.
- the spindle 23 is guided in the direction of its axis 38, that is, prevented from rotating, so that in this way the rotary movement of the electric motor 32 is converted into a purely vertical axial movement of the spindle 23 according to the double arrow 39. From this it is understandable that in this way, depending on the direction of rotation, the upper closure piece 12 can be extended upwards out of the brewing chamber 14 or into the brewing chamber 14 downwards, depending on the direction of rotation. It goes without saying that the extension process is only completed when the sieve 22, that is to say the deepest part of the upper closure piece 12, lies above the surface of the cover part 3, so that contact during the subsequent pivoting process into the parking position with the surface of the Cover part 3 is avoided.
- the vertical drive for the lower closure piece 13 is designed in principle in accordance with the design of the vertical drive of the upper closure piece 12, although this drive is designed for larger strokes.
- the worm gear 19 in the form of a worm 40 and a worm wheel 41 is connected downstream of the electric motor 20.
- the worm wheel 41 is in turn designed as a nut and has an internal thread 42 which cooperates with an external thread on the spindle 18.
- the spindle 18 is axially secured against rotation, so that in this way vertical movements of the lower closure piece 13 according to double arrow 43, depending on the direction of rotation of the electric motor 32, are possible.
- the rotary arm 24 is assigned an abutment 44, which is arranged in a fixed manner on the housing 2, 3 of the instantaneous water heater 1 and has a nose 46, which is expediently adjustable in height with the aid of a screw 45, which is formed by the rotary arm 24 when the ready position is reached, forming short distance of fractions of a mm is accessible.
- a nozzle 47 with a subsequent channel 48 is provided in the upper closure piece 12, via which the hot water is ultimately pushed through the sieve 22 and passed into the brewing chamber 14 or the compressed coffee powder tablet provided there.
- a coffee grinder not shown, is provided, through the outlet connection of which the ground coffee powder can be introduced approximately in the axis 9 above the brewing space 14 when the rotating arm 24 with the upper closure piece 12 is in the pivoted-down parking position .
- a filling funnel (not shown) can also be connected to the rotating arm 24 in order to exert a certain conductivity on the ground and falling coffee powder.
- the rotating arm For removing coffee powder from the surface of the lid part 3 in In this area, as well as for coffee powder residues resulting from the dry ejection of a leached tablet, the rotating arm preferably has two wipers 49 (FIG. 3), which clean the surface of the cover part 3 in succession during a pivoting movement.
- FIG. 2 shows a circuit diagram with the essential parts of the automatic coffee machine, the hydraulic lines being indicated in solid lines and the electrical lines in dashed lines.
- a cold water line 50 leads to a pump 51, which is controlled by an electronic control device 52 via an electrical line 53.
- a water line 54 leads from the pump 51 to a water flow meter 55 and from there to the nozzle of the flow heater 1 located on the lower part 2.
- a line 56 for hot water leads to a brewing valve 57 and from there as line 58 through the upper closure piece 12 into the brewing chamber 14.
- the brewing valve 57 is designed as a two / three-way valve, a line 59 leading to an outlet 60.
- An electrical line 61 leads from the electrical control device 52 to the water flow meter 55, an electrical line 62 to the heating coil 5 of the water heater 1, and lines connected in parallel to a temperature control in the water heater 1, which is not shown for the sake of clarity.
- An electric line 63 controls the brewing valve 57.
- Another line 64 leads to the axial drive 32, 35, 36 according to the double arrow 39 for the upper closure piece 12, a line 65 to the swivel drive 30, 29, 28 according to the double arrow 66 around the axis 26.
- Another Electrical line 67 leads from the control device 52 to the vertical drive 20, 40, 41 for the lower closure piece 13.
- FIG. 3 leaves the structural unit consisting of rotary arm 24 with the axial drive 32, 35, 36 and the swivel drive 30, 29, 28 detect.
- the two electric motors 30 and 32 are arranged with their axes 33 and 34 in parallel on the rotary arm 24 so that they pivot with it. The pivoting takes place about the axis 26 according to the double arrow 66, depending on the direction of rotation of the electric motor 30. It can also be seen how the two wipers 49 drive over the brewing chamber 14 or the adjacent wall of the cover part 3 and clean this surface. At the same time, this movement also results in dry ejection, ie the leached coffee powder tablet raised by the lower closure piece 13 can be removed by this movement.
- the position of the electric motor 20 can also be seen from FIG. All three motors 20, 30, 32 are designed and arranged relative to one another in such a way that a narrow brew group is formed.
- the function of the coffee machine is explained in the overview of the figures as follows: In the daily commissioning of the coffee machine z. B. at the beginning of breakfast time or the like.
- the control device 52 is activated.
- the brewing water is heated with the help of the heating coil 5, the brewing device 7 with its essential parts also being heated at the same time.
- the lower closure piece 13 is, for example, in the position shown in FIG. 1 and is consequently also heated, the pipe section 8 being flushed with water over the entire circumference.
- the lower part 2 and the lid part 3 of the housing of the instantaneous water heater 1 are also heated, so that the upper closure piece 12, which is provided on the rotating arm 24, together with the bearing 25, becomes correspondingly warm.
- the temperature control device in the interior 4 of the instantaneous water heater 1 indicates that the water has reached the required temperature, then the essential components of the brewing device 7 already have the corresponding temperature and the coffee machine is ready for operation.
- the first cup or a pot of coffee drink can be prepared by a further switching process, which is triggered mechanically on the control device 52.
- the rotary arm 24 remains in the park position with the upper closure piece 12 or it moves into this park position via the swivel drive 30, 29, 28, so that the brewing chamber 14 is accessible from above.
- the coffee grinder arranged in the axis 9 is set in motion by the control device 52 for the associated time unit (cup or jug), so that a corresponding portion of coffee powder falls into the brewing space 14 of the brewing device 7.
- the control device 52 controls the swivel drive 30, 29, 28, so that the rotary arm 24 with the upper locking piece 12 is swiveled in accordance with the double arrow 66 until the axis 38 is aligned with the axis 9 of the brewing device 7.
- the effective length of the rotary arm 24 does not change during this swiveling process, so that a relatively precise adherence to this coordinate is possible here. If the rotary drive has been terminated so precisely that the other coordinate for the aligned position of the two axes 38 and 9 is also given, there are no difficulties in moving the upper closure piece 12 into the pipe section 8.
- the play in the swivel drive 30, 29, 28th and the resulting mobility in connection with the design of the upper closure piece 12 and the tube section 8, in particular its upper end, are used to the exactly aligned position of the two axes 38 and 9 to reach.
- the play in the swivel drive 30, 29, 28 is therefore necessary, as it were, to enable this self-centering.
- the axial drive 32, 35, 36 is therefore actuated, so that the upper closure piece 12 has the inside diameter in both cases of the pipe section 8 retracts, to a point such as that shown in FIG. 1.
- the brewing chamber 14 is closed at the top by the seal 21.
- the closure piece 12 now remains at rest for a long time.
- the lower closure piece 13 is raised so that the loosely filled coffee powder of a tablet is compressed.
- the rotary arm 24 is supported under the nose 46 of the abutment 44, so that the bearing 25 is relieved accordingly.
- the electric motor 20 is briefly reversed so that the tablet is relieved. In this position, the actual brewing process can begin by activating the pump 51 via line 61 and the brewing valve 57 via line 63.
- a quantity of fresh water corresponding to the desired quantity of coffee beverage is introduced into the interior 4 of the instantaneous water heater 1 and a corresponding quantity of hot water is distributed over the line 58 through the upper closure piece 12 and via the sieve 22 into the brewing chamber 14, where the tablet of coffee powder is penetrated and the coffee beverage is dispensed via the hose 17 at the outlet.
- the brewing valve 57 is closed again, the control of the electric motor 20 causing the coffee powder tablet to be pressed or dry pressed. Then the spout of the coffee drink ends.
- the upper closure piece 12 is extended from the pipe section 8 with the aid of the axial drive 32, 35, 36 and swiveled away into the park position with the aid of the swivel drive 30, 29, 28.
- the vertical drive 20, 40, 41 the lower closure piece 13 is lifted simultaneously or in succession, so that the tablet from leached coffee powder is raised so far that the upper edge of the lower closure piece 13 with the upper edge the cover part 3 is aligned.
- the swivel drive 30, 29, 28 and with the help of the wipers 49 the dry coffee powder tablet is then conveyed away laterally on the cover part 3 and this area is cleaned.
- the pivot arm 24 pivots again into the park position and the lower locking piece 13 can be lowered. A new brewing process can then follow.
- control device 52 and the various drives as well as the other details of the device make it possible to control any intermediate steps and to carry out further measures with one and the same device.
- the amount of coffee powder for a jug of coffee drink must be greater than the amount of coffee powder for a cup of coffee drink, which is effected by appropriate timing of the coffee grinder and also by corresponding displacement control of the lower closure piece 13 relative to the upper closure piece 12.
- a small amount of coffee powder can be used for a pot of coffee than it is twice the amount of coffee powder for a cup.
